Overview
The TLC3702IDG4 is a dual micropower voltage comparator produced by Texas Instruments. It is designed to operate from a single supply and is compatible with modern HCMOS logic systems. This component is functionally similar to the LM339 but consumes one-twentieth of the power while maintaining similar response times. The TLC3702IDG4 features a push-pull CMOS output stage that can drive capacitive loads directly without the need for a power-consuming pullup resistor, reducing power dissipation and saving board space and component cost. The LinCMOS™ process used in this component offers superior analog performance, including low power consumption, high input impedance, low bias currents, and stable input offset voltages.
